Site description

An old quarry exposure of a section through the Upper Coal Measures strata beneath the limestone escarpment immediately to the west of the South Don Fault. The gates were locked and a close inspection not possible but the lower half of the section appeared to comprise massive reddened sandstone, overlain by cross-bedded pale yellow friable sandstone which does not have the typical darkened and weathered appearance of Carboniferous sandstone. They also contain occasional large vugs/nodules, which appear as discontinuous lenses.

At [SE 513 004], 100 m down the limestone escarpment from Cadeby, small exposures of reddened massive sandstone identified as Dalton Rock are seen in the road cutting.

In view of the rarity of good exposures in the Upper Coal Measures in Doncaster, further investigation of this site is recommended with the permission of the owners, Yorkshire Water.
